Digital viewfinder user interface for multiple cameras

ABSTRACT

An electronic device has multiple cameras and displays a digital viewfinder user interface for previewing visual information provided by the cameras. The multiple cameras may have different properties such as focal lengths. When a single digital viewfinder is provided, the user interface allows zooming over a zoom range that includes the respective zoom ranges of both cameras. The zoom setting to determine which camera provides visual information to the viewfinder and which camera is used to capture visual information. The user interface also allows the simultaneous display of content provided by different cameras at the same time. When two digital viewfinders are provided, the user interface allows zooming, freezing, and panning of one digital viewfinder independently of the other. The device allows storing of a composite images and/or videos using both digital viewfinders and corresponding cameras.

CROSS-REFERENCE TO RELATED APPLICATIONS

This Application claims the benefit of U.S. Provisional Application No. 62/151,955, entitled “DIGITAL VIEWFINDER USER INTERFACE FOR MULTIPLE CAMERAS,” filed on Apr. 23, 2015, which is hereby incorporated by reference in its entirety.

FIELD

The disclosed examples relate generally to user interfaces of electronic devices, particularly devices having built-in cameras.

BACKGROUND

Some portable electronic devices have built-in cameras. These devices may provide digital viewfinders for user-interaction with the cameras. The digital viewfinders may allow variable image zooming through the use of optical and/or digital magnification. Optical magnification provides better visual quality but introduces complexities in the device's optical train, as optical zooming is achieved by moving physical components (e.g., lenses) along a physical, optical train. Digital magnification avoids these complexities, thereby permitting more efficient device packaging, but may suffer in visual quality.

DESCRIPTION OF EMBODIMENTS

The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments.

Efficient device packaging allows desirable, highly-portable electronic devices to be designed and manufactured. But, some electronic device components complicate the design of smaller devices, particularly thinner ones. Camera sensors and related components constitute an example: they involve physical components organized along optical trains that lend to thicker designs. Consider, for instance, the ability of a camera (e.g., CCD sensor and related lenses) to perform variable optical zooming depends on the arrangement of moveable (e.g., motorized) lens(es) among an optical train. When incorporated into cellular phones, the usual orientation of camera components is at odds with the form-factor of the overall phone: the camera's optical train typically runs along the thickness of the device. The use of cameras of thinner design—such as fixed focal length cameras—introduces other issues. Namely, fixed focal length cameras do not have variable, optical zoom capabilities. While it is still possible to perform digital zooming, digital zooming impacts image quality.

The embodiments described herein include electronic devices that utilize multiple cameras to provide improved camera capabilities. In some embodiments, multiple cameras of fixed focal length are used with variable digital magnification to mimic optical zooming capabilities. The described embodiments also include complementary user interfaces that enable these improved camera capabilities.

Together, the described embodiments permit efficient packaging and production of thin and light devices, while improving the performance of the device's camera optical capabilities. The use of fixed focal length cameras is beneficial as they are thinner than their variable focal length counterparts. The use of multiple cameras permit an approximation of optical zoom even if the underlying cameras are not capable of variable optical magnification. Intuitive user interfaces allow users to leverage the benefits of multiple on-board cameras without placing undue cognitive burdens on the user, thereby producing a more efficient human-machine interface. In battery-operated embodiments, the described embodiments also conserve power and increase run-time between battery charges, as the use of fixed focal length cameras to simulate optical zooming avoids battery consumption by motorized lenses used in conventional variable, optical zooming cameras.

Below, FIGS. 1A-1B, 2, 3, 4A-4B, and 11 provide a description of exemplary devices that utilize multiple cameras to provide camera zooming, and other related capabilities. FIGS. 5A-5T, 6A-6G, and 7 illustrate exemplary user interfaces supporting these capabilities. These figures are also used to illustrate the processes described below, including those described in FIGS. 8A-8C, 9, and 10.

Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch.

The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as button(s), a physical keyboard, a mouse, and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments. Touch-sensitive display 112 is sometimes called a “touch screen” for convenience, and is sometimes known as or called a “touch-sensitive display system.” Device 100 includes memory 102 (which optionally includes one or more computer-readable storage mediums), memory controller 122, one or more processing units (CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. In some embodiments, microphone 113 has at least two microphones to support the performance of certain DSP functions. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more contact intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data. In some embodiments, peripherals interface 118, CPU 120, and memory controller 122 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

A quick press of the push button optionally disengages a lock of touch screen 112 or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g., 206) optionally turns power to device 100 on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen 112 is used to implement virtual or soft buttons and one or more soft keyboards.

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif.

A touch-sensitive display in some embodiments of touch screen 112 is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen 112 displays visual output from device 100, whereas touch-sensitive touchpads do not provide visual output.

A touch-sensitive display in some embodiments of touch screen 112 is described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

Touch screen 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 optionally also includes one or more optical sensors 164. FIGS. 1A and 1B show an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 optionally captures still images or video.

The term “camera” is used herein as encompassing an optical system that is formed by an optical sensor (e.g., 164) and one or more lenses through which light is projected to reach the optical sensor (and optionally, other related components). Such an optical system—a camera—can have a fixed focal length, meaning that the focal length, field of view, and optical magnification properties (if any) of the optical system is fixed, among other things. Cameras having a fixed focus length may also be described as having a prime lens. Or, a camera can have a variable focal length, meaning that the optical magnification properties of the optical system can change, such as by changing the position of one or more lenses with respect to the optical sensor within an optical train of the optical system. In some embodiments, device 100 has an optical sensor and corresponding lens(es) that form a camera of fixed focal length. In some embodiments, device 100 has an optical sensor and corresponding lens(es) that form a camera of variable focal length.

Moreover, device 100 can have one or more cameras of either design. In some embodiments, device 100 has two or more cameras located on a surface, for example, on its back, opposite touch screen display 112 on the front of the device, so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, device 100 has two or more cameras located on its front, so that the user's image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor 164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 164 is used along with the touch screen display for both video conferencing and still and/or video image acquisition.

When two or more cameras are located on a surface of device 100, the optical axes of the cameras is, optionally, arranged such that they are parallel. Put another way, the cameras capture overlapping fields of view, for example, at least 50%, at least 90%, or more, in various embodiments. The cameras preferably have different focal lengths, meaning that one camera is of a wider-angle design—has a wider field of view but lower optical magnification—while another camera is of a higher-magnification design—has a narrower field of view but higher native optical magnification.

Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled to intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor 165 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor 165 receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

Device 100 optionally also includes one or more proximity sensors 166. FIGS. 1A and 1B show proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 is, optionally, coupled to input controller 160 in I/O subsystem 106. Proximity sensor 166 optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A shows a tactile output generator coupled to haptic feedback controller 161 in I/O subsystem 106. Tactile output generator 167 optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion, such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor 165 receives tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

Device 100 optionally also includes one or more accelerometers 168. FIGS. 1A and 1B show accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 is, optionally, coupled to an input controller 160 in I/O subsystem 106. Accelerometer 168 optionally performs as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3) stores device/global internal state 157, as shown in FIGS. 1A, 1B and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 8-pin, 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices.

Contact/motion module 130 optionally detects contact with touch screen 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator(s) 167 to produce tactile outputs at one or more locations on device 100 in response to user interactions with device 100.

Text input module 134, which is, optionally, a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing; to camera 143 as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety.

Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module 152, FIG. 1A). In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripherals interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module 172, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177, or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 include one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170 and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event (187) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event (187) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2A illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 optionally also include one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally, executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In some embodiments, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, subscriber identity module (SIM) card slot 210, headset jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch screen 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

FIG. 2B illustrates the side of portable multifunction device 100 opposite touch screen 112 in accordance with some embodiments. As can be seen, device 100 includes cameras 214 and 216. Camera 214 is a wider-angle camera and camera 216 is a higher-magnification camera in some embodiments. While the cameras in FIG. 2B are shown on a side of portable multifunction device 100 that is opposite touch screen 112, it should be understood that in principle, the cameras could be positioned on any side of the device (e.g., a same side as touch screen 112), or an edge of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPUs) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to FIG. 1A), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above-identified elements in FIG. 3 is, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces that are, optionally, implemented on, for example, portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Icon 416 for telephone module 138, labeled “Phone,” which             optionally includes an indicator 414 of the number of missed             calls or voicemail messages;         -   Icon 418 for e-mail client module 140, labeled “Mail,” which             optionally includes an indicator 410 of the number of unread             e-mails;         -   Icon 420 for browser module 147, labeled “Browser;” and         -   Icon 422 for video and music player module 152, also             referred to as iPod (trademark of Apple Inc.) module 152,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 424 for IM module 141, labeled “Messages;”         -   Icon 426 for calendar module 148, labeled “Calendar;”         -   Icon 428 for image management module 144, labeled “Photos;”         -   Icon 430 for camera module 143, labeled “Camera;”         -   Icon 432 for online video module 155, labeled “Online             Video;”         -   Icon 434 for stocks widget 149-2, labeled “Stocks;”         -   Icon 436 for map module 154, labeled “Maps;”         -   Icon 438 for weather widget 149-1, labeled “Weather;”         -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”         -   Icon 442 for workout support module 142, labeled “Workout             Support;”         -   Icon 444 for notes module 153, labeled “Notes;” and         -   Icon 446 for a settings application or module, labeled             “Settings,” which provides access to settings for device 100             and its various applications 136.

It should be noted that the icon labels illustrated in FIG. 4A are merely exemplary. For example, icon 422 for video and music player module 152 are labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 359) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 357 for generating tactile outputs for a user of device 300.

Although some of the examples that follow will be given with reference to inputs on touch screen display 112 (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments, the touch-sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of device such as device 100 or 300 (FIGS. 1 and 3). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) may each constitute an affordance.

1. Dual-Camera Zoom Capabilities

Attention is now directed to devices and user interfaces that enable zooming of a digital viewfinder using content received from multiple cameras, with reference to FIGS. 5A-5T. FIG. 5A depicts exemplary device 500, which is device 100 or 300 (FIGS. 1 and 3) in some embodiments. Device 500 has two cameras 502-a and 502-b located on a surface opposite display 504. Cameras 502-a and 502-b are positioned such that they face the same direction and have overlapping fields of view. Cameras 502-a and 502-b have fixed, but different, focal lengths in the exemplary device 500, meaning that the cameras do not provide variable optical zooming capabilities, natively (e.g., zooming accomplished by the movement of one or more optical elements relative to each other so as to change the focusing of incoming light on the camera sensor behind the one or more optical elements). In some examples, the focal length of camera 502-b is twice as long as the focal length of camera 502-a, resulting in camera 502-a having a wider field of view but lower optical magnification, and camera 502-b having a narrow field of view but higher optical magnification. Camera 502-a is also referred to as a “wider-angle camera,” while camera 502-b is referred to as a “higher-magnification camera.”

Display 504 is touch screen 112 (FIG. 1A) or display 340 (FIG. 3A) in some embodiments. Display 504 shows camera user interface 506 provided by a camera application of the device. Digital user interface 506 has digital viewfinder 508 for displaying visual content received from one or more of wider-angle camera 502-a and/or higher-magnification camera 502-b. Viewfinder 508 updates dynamically, meaning that its content changes as objects within the field of view of the viewfinder move with respect to device 500.

In some embodiments, viewfinder 508 displays content from wider-angle camera 502-a or higher-magnification camera 502-b depending on the viewfinder's zoom setting: when the zoom setting of viewfinder 508 is less than a threshold zoom value, viewfinder 508 displays content from one camera (e.g., wider-angle camera 502-a) of device 500. When the zoom setting of viewfinder 508 exceeds the threshold zoom value, digital viewfinder 508 displays content from the other camera of device 500 (e.g., higher-magnification camera 502-b). Because higher-magnification camera 502-b enjoys a greater amount of optical magnification natively, switching from camera 502-a to camera 502-b has the effect of magnifying (e.g., zooming) viewfinder content using the native optical properties of camera 502-b.

In addition to switching between the display of content from different cameras in response to whether a zoom setting exceeds a threshold zoom value, viewfinder 508 provides digital zooming of content, meaning that, for example, while viewfinder 508 is displaying content from wider-angle camera 502-a, viewfinder 508 can perform digital magnification on the content, responsive to changes in zoom setting, proportionately.

Notably, by using fixed camera 502-a to capture wider-angle (but lower-magnification) content and using fixed camera 502-b to capture higher-magnification (but narrower) content, device 500 provides the benefit of higher-quality, optical zooming with the thinner packaging advantages of cameras with fixed focal-length lenses (e.g., “fixed focal length cameras”). As used here, the term “capturing” visual content from a camera refers to using the light that enters the camera to obtain, with an optical sensor(s) (e.g., 164), visual information that can be displayed on a display screen such as display 504.

Camera user interface 506 has affordance 516 for storing visual content into visual media such as an image file or video file. As used here, “storing” captured visual content refers to saving the content into a long-term memory storage, such as by creating an image or video file having data representing the captured content in a non-volatile memory area of device 500. In the depicted example, when the zoom setting of viewfinder 508 is less than a threshold zoom value, responsive to activation of affordance 516, device 500 stores content from wider-angle camera 502-a into an image file, consistent with the composition shown in viewfinder 508. When the zoom setting of viewfinder 508 exceeds the threshold zoom value, the device stores visual content from higher-magnification camera 502-b as an image file instead. Thus, device 500 stores visual content from a wider-angle camera when the user desires a wider-angled composition, and stores content from a higher-magnification camera when the user desires emphasis of an object of interest, such as house 520.

Also, viewfinder 508 has zoom setting slider bar 510 and current zoom setting indicator 512. The term “zoom setting” refers to a value reflective of the overall magnification that is applied to viewfinder content. This overall magnification can account for optical and/or digital magnification. “Optical magnification” refers to the magnification arising from the physical properties of a camera (e.g., CCD and lens(es)) and is sometimes referred to as base magnification. A camera of fixed focal length design provides a fixed optical magnification, if any. A camera of variable focal length design can provide variable optical magnification. In contrast, “digital magnification” refers to digital enlargement of content received from a camera that may (but need not) have already experienced optical magnification.

The length of slider bar 510 represents the range over which digital viewfinder 508 can be zoomed (through digital and/or optical magnification). The position of current zoom setting indicator 512 indicates the current level of zoom. In the illustrated example, when indictor 512 is located at the left end of slider bar 510, digital viewfinder 508 displays content from wider-angle camera 502-a at its native level of optical magnification, without digital magnification. When indicator 512 is located at the right end of slider bar 510, viewfinder 508 displays content from higher-magnification camera 502-b at a maximum level of digital magnification. In-between, viewfinder 508 displays content from one of cameras 502 with an amount of digital magnification (corresponding to the position of indicator 512) in addition to the native optical magnification of the camera being used.

Slider bar 510 includes optional threshold zoom setting indicator 514 representing the value of zoom at which viewfinder 508 switches between the use of content from wider-angle camera 502-a to higher-magnification camera 502-b. As used here, the term “source camera” refers to the camera that is providing the content being displayed in a digital viewfinder such as viewfinder 508. Viewfinder 508 includes optional source camera indicator 518, which displays a value indicative of the source camera. Source camera indicator 518 in FIG. 5A shows the verbiage “1×” to indicate that a lower-magnification, for example, wider-angle camera 502-a, is currently providing content to the viewfinder. Source camera indicator 518 can show alternative verbiage (e.g., “2×”) when a higher-magnification camera, for example, camera 502-b, is providing content to the viewfinder.

Turning to FIG. 5B, when device 500 detects movement of current zoom setting indicator 512 from its position in FIG. 5A in a rightward direction, viewfinder 508 enlarges its content. In embodiments utilizing fixed focal length cameras, this enlargement is provided by digital magnification of content (e.g., from wider-angle camera 502-a). Also, the change in zoom setting corresponds to the magnitude of the user input, meaning that content in viewfinder 508 zooms continuously as the user continues to move indicator 512. In some embodiments, the change in zoom setting is proportional to the magnitude of input movement.

When continued movement of indicator 512 results in the indicator being moved across threshold zoom setting indicator 514, viewfinder 508 switches from displaying content from wider-angle camera 502-a to displaying content from higher-magnification camera 502-b. Because higher-magnification camera 502-b provides higher (native) optical magnification, a lesser amount of digital magnification (if any) is needed to maintain the overall size of the viewfinder's content.

As the user continues to move indicator 512 rightward of threshold zoom setting indicator 514, viewfinder 508 applies digital magnification to the content from higher-magnification camera 502-b correspondingly and, optionally, proportionately with the magnitude of input movement. In this way, zoom setting slider bar 510 and current zoom setting indicator 512 constitute a “slider” control that governs the zoom setting of viewfinder 508 over the functional ranges of multiple cameras.

This zooming capability is beneficial in at least two ways. First, because camera 502-a has a wider field of view than camera 502-b, viewfinder 508 can leverage wider-angle camera 502-a to provide more expansive visual compositions, allowing for more objects of interest to be included in an image taken with device 500 for example. Conversely, because camera 502-b has higher native optical magnification, viewfinder 508 can leverage higher-magnification camera 502-b to provide a targeted composition, allowing for a crisper, magnified view of one object of interest among multiple nearby objects. When implemented using cameras of fixed focal lengths, as is the case in the depicted embodiment, device 500 leverages the relatively simpler designs of fixed focal length cameras to impart higher-quality variable zoom functionality in thin form-factor devices. Second, viewfinder 508 does not require the user's active management of source camera selection, even as the user zooms through the useful ranges though of multiple source cameras, thereby reducing the cognitive burden on the user.

Attention is now directed to more techniques for controlling zoom settings, in addition to the use of a slider control, provided by viewfinder 508 in some embodiments. FIGS. 5C and 5D depict the use of touch input such as tapping input and de-pinching and/or pinching input to change the zoom setting of viewfinder 508. As depicted in FIG. 5C, user instruction to zoom viewfinder 508 can be a tap input such as single-finger tap input 522 and/or two-finger tap input 524. As seen in FIG. 5D, responsive to either input 522 or 524, viewfinder 508 zooms into the displayed content (e.g., house 520) by switching to the use of content from higher-magnification camera 502-b (optionally applying digital magnification onto the received content). Viewfinder 508 also re-positions current zoom level indicator 512 to reflect the updated zoom setting. Further, viewfinder 508 updates source camera indicator 518 to indicate that viewfinder 508 is in a higher-magnification setting, for example, by displaying the verbiage of “2×” to indicate that viewfinder 508 is displaying content from a higher-magnification camera of the device. Although not shown, it is noted that finger taps 522 and 524 can each involve a single tap or multiple taps. In some embodiments, input 522 is a single-finger, double-tap touch input on display 504 or a touch-sensitive surface associated with display 504.

Attention is now directed to additional techniques for controlling viewfinder zoom settings, particularly those related to the behavior of viewfinder 508 as its zoom setting is adjusted at or near the threshold value represented by threshold zoom setting indicator 514, with reference to FIGS. 5E-5K. FIG. 5E depicts viewfinder 508 displaying an object of interest—house 520—at relatively zoomed-out setting using a low amount of digital magnification on content obtained from camera wider-angle 502-a. This zoom setting is confirmed by the position of current zoom setting indicator 512 towards the left end of zoom setting slider bar 510, as well as the indication of “1×” in source camera indicator 518. While displaying house 520, device 500 receives a de-pinching input represented by touches 526.

Turning to FIG. 5F, de-pinching input 526 causes viewfinder 508 to zoom-in, through digital magnification, onto the content from wider-angle camera 502-a. As the touch contacts of touches 526 move apart, the viewfinder zooms correspondingly. This change in zoom setting results in an enlargement of the displayed house 520 and a corresponding movement of current zoom level indicator 512 in the rightward direction towards threshold indicator 514. In the depicted example, the magnitude of content enlargement and movement of indicator 512 are proportional to the magnitude of de-pinching input 526.

FIG. 5G depicts the behavior of viewfinder 508 responsive to continued de-pinching input 526, which is now of sufficient magnitude to move the zoom setting of the viewfinder beyond the threshold zoom setting represented by indicator 514. But, viewfinder 508 ceases to zoom beyond the threshold zoom setting, despite the continued de-pinching movement of input 526. In this way, threshold zoom setting indicator 514 provides a “detent” feature, emphasizing to the user that the end of the useful zoom range of one camera (e.g., wider-angle camera 502-a) has been reached and that further zooming operations will cause the device to switch from using the wider-angle camera to using the higher-magnification camera.

The detent can be overcome. In some embodiments, the detent is overcome if a user continues de-pinching input 526 by a sufficient magnitude after the viewfinder's zoom setting has reached the threshold value of indicator 514. FIGS. 5H and 5I depict this aspect. As seen in FIG. 5H, device 500 receives continued movement of de-pinching input 526 after the viewfinder's zoom setting has reached the threshold represented by indicator 514. Viewfinder 508 determines whether this continued input has a magnitude exceeding a threshold magnitude, for example, a predetermined threshold distance. If the continued movement is below the threshold magnitude, the zoom setting of viewfinder 508 remains stationary, as seen in FIG. 5J. If the continued movement of de-pinching input 526 exceeds the threshold magnitude, viewfinder 508 switches source camera to higher-magnification camera 502-b, meaning that zooming resumes, as seen in FIG. 5I.

When viewfinder 508 resumes zooming, the change in overall zoom setting is proportional to the overall movement of de-pinching input 526, in some embodiments. That is, once the continued movement of de-pinching input 526 overcomes the detent, viewfinder 508 reacts as though the detent had not occurred: the zoom setting of the viewfinder catches up with the overall magnitude of the de-pinching input. In some embodiments, when viewfinder 508 resumes zooming, the change in zoom setting is proportional to only the post-detent movement of de-pinching input 526. Put another way, in these embodiments, a portion of the movement of de-pinching input 526 is consumed to overcome the detent.

In some embodiments, the detent is overcome when a user provides a second, separate de-pinching input after releasing input 526. FIGS. 5J and 5K illustrate this aspect. As seen in FIG. 5J, device 500 receives separate de-pinching input 528, after previous de-pinching input 526 is removed (e.g., after detecting liftoff of one or more of the contacts of de-pinching input 526). In response to this additional input 528, viewfinder 508 zooms beyond the zoom value of threshold indicator 514, meaning that viewfinder 508 switches from displaying content from wider-angle camera 502-a to displaying content from higher-magnification camera 502-b. As seen in FIG. 5K, house 520 is enlarged as compared with FIG. 5J. The higher level of zoom is also confirmed by the corresponding movement of current zoom setting indicator 512 and by the use of the verbiage “2×” in source camera indicator 518.

It is noted that while the “detent” features described using FIGS. 5E-5K are based on de-pinching and/or pinching touch inputs, the described features can function with other forms of user input. For example, the “detent” feature would also function with user input in the form of a touch movement of current zoom setting indicator 512 across threshold indicator 514 and/or depression of a mechanical zoom button or movement of zoom setting indicator 512 using a cursor and input device such as a mouse/trackpad.

Attention is now directed to still additional zoom-related features with reference to FIGS. 5L-5N. Turning to FIG. 5L, while viewfinder 508 is displaying content from wider-angle camera 502-a, device 500 detects input 530 at a location of display 504. Input 530 is a single-finger tap input in the depicted example. As seen in FIG. 5M, responsive to input 530, viewfinder 508 displays boundary box 532 indicating the area that viewfinder 508 is to zoom into. After displaying boundary box 532 momentarily, viewfinder 508 zooms into the indicated area, as seen in FIG. 5N. Although not shown, boundary box 532 has a dotted perimeter in some embodiments. Although not shown, boundary box 532 flashes when it is displayed in some embodiments.

In the foregoing examples of FIGS. 5A-5N, viewfinder 508 includes a zoom setting slider bar 510 that represents the useful zoom ranges of multiple cameras. Attention is now directed to other exemplary implementations of slider bars, particularly embodiments where a slider bar represents the range of only the source camera of a viewfinder, meaning that the slider acts an indicator of digital magnification (on content from a source camera), but not overall zoom (e.g., digital together with optical magnification).

This aspect is illustrated in FIGS. 5O-5Q. As seen in FIG. 5O, source camera indicator 518 indicates that the current source camera is wider-angle camera 502-a. The width of zoom setting slider bar 550 thus depicts the zoom range of wider-angle camera 502-a. Slider bar 550 need not include a discontinuity (e.g., a threshold value indicator) to signal the boundary between separate source cameras.

Responsive to input 538 representing user instructions to increase zoom, viewfinder 508 shows boundary box 540 identifying the area to be zoomed-into, as seen in FIG. 5P. After displaying boundary box 540 momentarily, viewfinder 508 zooms into the identified area by switching to the display of content from higher-magnification camera 502-b, as seen in FIG. 5Q (and, optionally, applies a digital magnification to content received from camera 502-b).

Furthermore, in the depicted embodiment, the amount of digital magnification that is applied to content from a source camera remains constant before and after the switch in source cameras. Device 500 accounts for the amount of digital magnification being applied onto content from wider-angle camera 502-a before the switch (e.g., FIG. 5O), and applies the same amount of digital magnification onto content from higher-magnification camera 502-b after the switch (e.g., FIG. 5Q). The positioning of current zoom setting indicator 552 thus remains stationary during source camera switches, even though viewfinder content becomes enlarged due to the higher native optical magnification of the new source camera. This treatment of indicator 552 beneficially reduces jitter in the zoom slider control during source camera switches.

Attention is now directed to techniques for directly selecting a source camera to be used as source for viewfinder 508, in some embodiments, with reference to FIGS. 5R-5T. As seen in FIG. 5R, while viewfinder 508 is displaying content from one camera (e.g., wider-angle camera 502-a), the viewfinder shows camera selection affordance 546. Camera selection affordance 546 provides a preview of content from another camera (e.g., higher-magnification camera 502-b). That is, affordance 546 acts as a miniature viewfinder by showing a dynamic thumbnail image sourced from an alternate camera of device 500.

Camera selection affordance 546 is particularly useful where a user wishes to explore the impact of digital magnification versus optical magnification for artistic effect, for example. In these examples, viewfinder 508 permits the user to enlarge the content of a wider-angle camera to the degree where the digitally magnified content appears grainy. FIG. 5S depicts the digital magnification of house 520 to this extent (as depicted by the use of dotted lines). Simultaneous with this display of house 520, viewfinder 508 provides affordance 546 a preview from higher-magnification camera 502-b, suggesting to the user that an alternate source of content is available.

When device 500 detects input 548 on affordance 546, viewfinder 508 switches from the display of content from wider-angle camera 502-a to the display of content from higher-magnification camera 502-b. Leveraging the higher native optical magnification properties of camera 502-b, viewfinder 508 provides a crisper version of house 520 as compared with camera 502-a at equivalent levels of overall (e.g., digital and optical) magnification. While viewfinder 508 displays content from higher-magnification camera 502-b, affordance 546 updates to display content from wider-angle camera 502-a dynamically.

In the depicted embodiment, the amount of overall magnification due to digital and optical magnification that is applied to content from a source camera remains constant before and after the switch in source cameras. For example, device 500 accounts for the amount of digital magnification that is applied to the base optical magnification of wider-angle camera 502-a before the switch in source cameras, and determines a corresponding (e.g., lower) amount of digital magnification that should be applied to content from higher-magnification camera 502-b after the switch, so that the combined effects of digital and native optical magnification with respect to viewfinder objects remain the same before and after switching source cameras. As can be seen by comparing FIGS. 5S and 5T, house 520 appears at approximately the same size before and after the switch in source cameras. This treatment of viewfinder content beneficially reduces jitter in the viewfinder display area during source camera switches.

In some embodiments, camera selection affordance 546 is displayed only after a user zooms viewfinder 508 beyond a threshold zoom setting. This withholding of the display of affordance 546 reduces on-screen clutter and increases the amount of display area that is available for previewing content from an active source camera.

In some embodiments, camera selection affordance 546 does not provide a dynamic preview of content, but is instead fashioned as an “enhance” button, such as by displaying affordance 546 as a button labeled “enhance”. In these embodiments, when the “enhance” button is selected, viewfinder 508 switches source cameras, and performs the necessary calculations to maintain the on-screen size of viewfinder content. By switching source cameras to provide a crisper showing of viewfinder content at the same size, affordance 546 provides the visual effect of enhancing the displayed viewfinder content.

In the examples of FIGS. 5A-5T, device 500 switches between displaying content from multiple cameras responsive to user interaction with viewfinder 508. The on-screen switching of source cameras can, however, introduce visual artifacts into viewfinder 508 that distract from the overall user experience. For example, viewfinder 508 may appear jittery if content from one camera is not aligned with content from another camera during a switch of source cameras. This effect, due to parallax, increases as the distance between the cameras increases and decreases as the distance between the cameras and the subject increases.

Attention is now directed to other features that mitigate negative visual impacts while zooming the viewfinder. In some embodiments, viewfinder 508 provides a transition effect during the switching of source cameras. In some examples, the transition effect is a cross-fade effect in which content from both cameras are blended and displayed momentarily. In some examples, the transition effect is a cross-fade effect in which content from both cameras are simultaneously displayed atop one another as translucent overlays, momentarily. In some examples, the transition effect is a blur effect in which content from one or both cameras is blurred momentarily. The level of blending, translucency, and/or blur is adjusted dynamically as the zoom setting changes in some embodiments. These transition effects mask minor misalignments in viewfinder content positioning and/or changes in viewfinder object sizes resulting from the switch in source camera, thereby improving the perceived quality of device 500.

In some embodiments, viewfinder 508 reduces parallax associated with switching source cameras. As the cameras of device 500 may not be concentric, but are rather placed side by side, switching between source cameras can produce minor parallax caused by the different positions (or vantage points) of the cameras relative to the subject. To reduce the appearance of parallax within viewfinder 508 in these embodiments, device 500 identifies a portion of viewfinder content that is to survive the switch (e.g., a point of interest such as a portion of house 520), and performs calculations necessary to maintain the portion of interest at the same location of display 504. More specifically, viewfinder 508 shifts as necessary the visual content received from the new source camera and/or the old source camera so that the point of interest is displayed at the same pixel(s) of display 504 before and after the switch in source cameras. If the point of interest is selected so that it include the region of the visual content that the user is interested in and likely looking at (e.g., by selecting a focus point selected by the user or a centroid of a pinch input), the shift caused by parallax when switching between the two cameras is reduced for the region of the visual content that the user is interested in (even though a greater shift caused by parallax will occur in other regions of the visual content).

In some embodiments, the point of interest is specified by the user, such as the location of a tap or the centroid of a de-pinching input. In some embodiments, the point of interest is specified by the device, such as by identifying a portion of viewfinder content that exhibits pixel-to-pixel variations indicative of a foreground object (as opposed to background), and that to survive the camera switch operation. In this way, device 500 reduces the appearance of parallax caused by differences in camera vantage points.

In some embodiments, visual artifacts in the viewfinder that can be caused by switching source cameras is avoided altogether by confining viewfinder 508 to the display of content from a preferred camera, regardless of zoom setting. For instance, because wider-angle camera 502-a has a field-of-view that subsumes the field of view of the higher-magnification camera 502-b, viewfinder 508 can rely on digital magnification of content from wider-angle camera 502-a to mimic the display of content from higher-magnification camera 502-b, without resorting to the use of higher-magnification camera 502-b.

In some embodiments, when a user elects to store a captured picture, for example by activating affordance 516, device 500 identifies and uses the camera most optimal for capturing content at the overall zoom setting to create the output media. For example, if viewfinder 508 is at a zoom setting below the threshold value represented by indicator 514 (FIG. 5A), device 500 stores visual information from wider-angle camera 502-a, as the same image composition cannot be obtained from camera 502-b, which has a narrower field of view. Conversely, if viewfinder is 508 at a zoom setting above the threshold value, device 500 stores visual information from the higher optical-magnification camera 502-b, as the higher-magnification camera enjoys greater clarity using native optical magnification.

2. Dual Digital Viewfinder

Attention is now directed to embodiments featuring dual, simultaneously displayed digital viewfinders for creating still images, with reference to FIGS. 6A-6E. As seen in FIG. 6A, device 600 has cameras 602-a and 602-b located on a side opposite of display 604. Display 604 provides camera user interface 606 having dual digital viewfinders 608-a and 608-b. Viewfinder 608-a displays content from one camera (e.g., camera 602-a) while viewfinder 608-b displays content from the other camera (e.g., camera 602-b), simultaneously. Camera 602-a is a wider-angle camera and camera 602-b is a higher-magnification camera, in some embodiments.

User interface 606 allows a user to manage the compositions of digital viewfinders 608-a and 608-b independently, such as by zooming, panning, and freezing viewfinder content. User interface 606 also allows a user to store visual information from both cameras simultaneously. In some embodiments, visual information from both cameras are stored or otherwise associated with one another, forming what is referred to as a “diptych” image.

As seen in FIG. 6A, viewfinder 608-a, which displays content from wider-angle camera 602-a, allows viewfinder objects including house 612, tree 614, and car 616 to be previewed together. In contrast, viewfinder 608-b, which displays content from higher-magnification camera 602-b, allows house 612 and tree 614 to be previewed at a larger size, but is unable to capture car 616 within its narrower field of view.

Turning to FIG. 6B while referring back to FIG. 6A, in response to exemplary user input 620, which is a touch movement within the display area of viewfinder 608-a, viewfinder 608-a pans rightward, effectively removing tree 614 from view. Viewfinder 608-b does not pan in response to user input 620, as the input falls outside (or, optionally because the input starts outside) of the display area of viewfinder 608-b.

Turning to FIG. 6C while referring back to FIG. 6B, in response to exemplary user input 622, which is a de-pinching touch input within the display area of viewfinder 608-a, viewfinder 608-a zooms into displayed objects 612 and 616. Viewfinder 608-b does not zoom in response to user input 622, as the input falls outside (or, optionally because the input starts outside) of the display area of viewfinder 608-b.

Turning to FIG. 6D while referring back to FIG. 6C, in response to exemplary user input 624, which is tap within the display area of viewfinder 608-a, viewfinder 608-a freezes its displayed content, meaning that the displayed content becomes static and no longer updates dynamically based on movement of objects with respect to camera 602-a. Viewfinder 608-b does not freeze in response to user input 624, as the input falls outside the display area of viewfinder 608-b. Thus, as device 600 pans to the left, the content of viewfinder 608-b updates dynamically by panning to the left. Meanwhile, viewfinder 608-a, which is frozen, remains fixed despite the movement of device 600.

In some embodiments, the content of a frozen digital viewfinder can still be manipulated by a user, such that the image is, optionally, zoomed in or out, panned, rotated, or subject to digital filters and other editing effects. To support these types of image manipulation, particularly zooming out and panning, the freezing of viewfinder 608-a in some embodiments involves capturing camera content beyond what is immediately needed (e.g., in terms of image size and resolution) for display in a frozen viewfinder. The extra content can be later revealed responsive to zooming and panning of the frozen viewfinder as appropriate.

In some embodiments, a frozen viewfinder unfreezes in response to an additional user input within its display area. Exemplary user inputs for unfreezing a frozen viewfinder include a single-finger tap, a double-finger tap, and a de-pinching/pinching input. In some embodiments, upon unfreezing, a viewfinder immediately resumes displaying source camera content dynamically. In some embodiments, upon unfreezing, a viewfinder continues to display information statically (e.g., with the composition that the device had displayed while frozen) until an additional input (e.g., to zoom or pan the viewfinder) is detected, at which time the unfrozen viewfinder begins to display camera content dynamically again.

Turning to FIGS. 6E and 6F, in response to exemplary user input 620, which is a two-finger touch movement 628 in a horizontal direction, device 600 creates diptych image 630 using content as seen in frozen viewfinder 608-a and the content as seen in viewfinder 608-b sourced from camera 602-b. In some embodiments, diptych image 630 is stored into the non-volatile storage of device 600 as one or more associated files such that diptych image 630 be later retrieved from a library collection of visual media content.

For brevity, it is noted that viewfinder 608-b can be zoomed, panned, and/or frozen in the same manner as described with reference to viewfinder 608-a. Further, although not shown, each of viewfinders 608-a and 608-b can display one or more affordances for controlling and/or indicating the zoom setting of respective viewfinder, such as the zoom “slider” controls described with respect to FIGS. 5A-5T. Further still, although the discussion of FIGS. 6D and 6E relies on exemplary input 694 for freezing a viewfinder, in some embodiments, the release of an existing input is taken as an instruction to freeze a viewfinder. For example, a viewfinder can freeze as a user releases the touch input that was used to pan the viewfinder's displayed content (e.g., release of panning input 620 in FIG. 6B), meaning that the release of an input can itself be recognized as an input for freezing a viewfinder, in these embodiments.

Also, although the discussion of FIGS. 6A-6F involve the use of certain exemplary inputs for triggering specific viewfinder effects (e.g., single-finger single-tap to freeze a viewfinder), one of ordinary skill in the art would appreciate that other types of input can be used to affect viewfinder behavior. For example, panning can be performed using multi-finger inputs, zooming can be performed using a hardware button of device 600, freezing can be performed using multiple taps, and the storing of viewfinder content into a diptych image can be invoked using touch inputs other than a two-finger horizontal swipe, without departing from the principal capabilities of device 600. Further, device 600 can interpret parts of a continuous touch gesture as containing multiple inputs for controlling viewfinders, in some embodiments. For example, device 600 can interpret a touch gesture that includes a two-finger de-pinching component, followed by a lateral movement of the two fingers, and followed by a release of one of the two fingers, as containing three inputs: the initial de-pinching input zooms a relevant viewfinder, the later two-finger lateral movement pans the viewfinder, and the subsequent single-finger release freezes the viewfinder.

Attention is now directed to embodiments featuring dual, simultaneously displayed digital viewfinders for creating videos, with reference to FIG. 7. As seen in FIG. 7, device 700 has cameras 702-a and 702-b located on a side opposite of display 704. Display 704 provides camera user interface 706 having dual digital viewfinders 708-a and 708-b. Viewfinder 708-a displays content from one camera (e.g., camera 702-a) while viewfinder 708-b displays content from the other camera (e.g., camera 702-b). Camera 702-a is a wider-angle camera and camera 702-b is a higher-magnification camera in some embodiments.

User interface 706 allows a user to manage the compositions of digital viewfinders 708-a and 708-b independently, such as by zooming and panning viewfinder content separately. User interface 706 also allows a user to initiate simultaneous recording (e.g., storing) of visual information from both cameras. As seen in the example of FIG. 7, device 700 can simultaneously store a wider-angle video based on the composition of viewfinder 708-a, as well as a more zoomed-in video based on the composition of higher-magnification viewfinder 708-b. In the illustrated example, device 700 is storing a court-side view of a volleyball serve using the wider-angle composition of viewfinder 708-a, as well as an enlarged view of a single volleyball player based on the higher-magnification composition of viewfinder 708-b.

In some embodiments, user interface 706 permits user control of the frame rate at which “video” is stored. For example, user interface 706 can store visual information from camera 702-a (as shown in viewfinder 708-a) at 24 frames per second (fps), which is accepted in filmography as sufficient for producing content perceived by human users as video. Simultaneously, visual information from camera 702-b (as shown in viewfinder 708-b) can be stored at a higher frame rate, such as 48 fps, to enable slow motion playback of the volleyball player's serve in detail. Conversely, visual information from camera 702-b can be stored at the typical 24 fps while visual information from camera 702-a is stored at a lower rate of three fps so as to impart a snapshot quality to the “video” taken from camera 702-a.

In some embodiments, user interface 706 permits user control of other visual characteristics that are applied to a stored video. In some examples, content from the first and second cameras are stored at different resolutions. In some examples, content from the first and second cameras are stored using different image enhancement techniques, including image processing techniques that alter the appearance of an image or video, such as its brightness, contrast, saturation, hue, color intensity, exposure, color scheme, and/or the application of filters.

In some embodiments, content stored from one camera and used as an identifier for content stored from another camera. For example, a still image obtained from wider-angle camera 702-a is used as a thumbnail image to represent a video file created based on content from higher-magnification camera 702-b. Device 700 can display the thumbnail image (or other graphical representation) of the stored video among a library of videos for later playback selection.

In some embodiments, non-visual media is captured and stored with the visual content from the first and second cameras. For example, non-visual media includes audio media captured by a microphone of device, 100, 300, or 500, such as microphone 113 (FIG. 1A). In some embodiments, a user can trigger audio playback while device 700 is displaying a library collection of stored videos, ahead of a user's selection of a stored video for visual playback. In this way, the audio component can assist the user's selection of a video for playback. In some embodiments the enhanced-zoom mode of camera operation described with reference to FIGS. 5A-5T, the dyptich mode of camera operation described with reference to FIGS. 6A-6G, and the multimedia-capture mode of camera operation described with reference to FIG. 7 are all modes of operation of the same set of cameras, and a user can switch between these modes depending on the situation and the user's preferences and save media captured in the different modes of operation to a same camera roll or other media gallery.

3. Exemplary Processes

FIGS. 8A-8C are flow diagrams illustrating exemplary process 800 for providing viewfinder zoom capabilities using multiple cameras in accordance with some embodiments, such as those described above with reference to FIGS. 5A-5T. Process 800 is carried out by device 500 (FIG. 5), which is, optionally, electronic device 100 or 300 (FIGS. 1A and 3A), in some embodiments.

At block 802, the electronic device displays a digital viewfinder showing content from one of at least two cameras. An exemplary digital viewfinder is viewfinder 508 (FIGS. 5A-5T). Exemplary cameras include wider-angle camera 502-a and higher-magnification camera 502-b (FIGS. 5A-5T). Viewfinder content is displayed at a certain zoom setting.

At block 804, the electronic device detects user input representing a user instruction to store visual media. An exemplary user instruction to store visual media is the activation of affordance 516 in camera user interface 506 (FIGS. 5A-5T).

At block 806, responsive to the user input, a determination is made as to whether the zoom setting is above or below a threshold zoom value. If the zoom setting is below the zoom threshold value, then processing proceeds to block 808 where content from a first camera (e.g., wider-angle camera 502-a) is stored. If the setting is above the zoom threshold value, then processing proceeds to block 810 where content from a second camera (e.g., higher-magnification camera 502-b) is stored. Storing content from a camera includes creating an image or video file, in a non-volatile memory of the electronic device, in some embodiments.

Block 802 optionally includes sub-block 802-a. As depicted in FIG. 8B, during sub-block 802-a, the selection of camera content for display in the viewfinder is made by determining whether the zoom setting is above or below a threshold zoom value. If the zoom setting is below the threshold zoom value, then content is displayed from a first camera (e.g., wider-angle camera 502-a). If the setting is above the threshold zoom value, then content is displayed from a second camera (e.g., higher-magnification camera 502-b).

Block 802 optionally includes sub-block 802-a. As depicted in FIG. 8B, during sub-block 802-b, the electronic device switches the source camera of its viewfinder responsive to user input representing an instruction to change viewfinder source camera. The user input is an activation of an on-screen camera selection affordance (e.g., affordance 546 in FIG. 5S) in some examples. The user input is a tap on the viewfinder (e.g., tap 522 or 524 in FIG. 5C, tap 530 in FIG. 5L, or tap 538 in FIG. 5O) in some examples.

Block 802 optionally includes sub-block 802-c. As depicted in FIG. 8C, during sub-block 802-c, the electronic device detects user input representing a request to change the zoom setting from a value below to a value greater than the threshold zoom value. Exemplary user input to change the zoom setting include a pinching touch input, a de-pinching touch input, a touch movement, one or more taps, depression of a hardware button, so forth. Responsive to the user input, the electronic device zooms the viewfinder by displaying content from the first camera (e.g., wider-angle camera 502-a) and then switching to displaying content from the second camera (e.g., higher-magnification camera 502-b). In addition, before switching to the second camera, content from the first camera (e.g., wider-angle camera 502-a) is digitally magnified responsive to the user input.

Block 802 optionally includes sub-block 802-d. As depicted in FIG. 8C, during sub-block 802-d, the electronic device detects user input representing a request to change the zoom setting to a value greater than the threshold zoom value. Responsive to the user input, the electronic device zooms the viewfinder by digitally magnifying content from the first camera (e.g., wider-angle camera 502-a in FIG. 5A), but does not switch to displaying content from the second camera (e.g., higher-magnification camera 502-b in FIG. 5B). Rather, the viewfinder ceases to zoom beyond the maximum zoom level of the first camera (e.g., wider-angle camera 502-a). Upon pausing at the maximum zoom level of the first camera, the viewfinder switches to displaying content from the second camera (e.g., higher-magnification camera 502-b) under some conditions. For example, the viewfinder switches source camera when the continued movement of the detected user input exceeds a threshold magnitude. As another example, the viewfinder switches source camera when a separate, second user input representing a request to change the zoom setting to a value greater than the threshold zoom value is detected.

FIG. 9 is a flow diagram illustrating exemplary process 900 for storing visual content using multiple cameras in accordance with some embodiments, such as those described above with reference to FIGS. 6A-6F. Process 900 is carried out by device 600 (FIG. 6), which is, optionally, electronic device 100 or 300 (FIGS. 1A and 3A), in some embodiments.

At block 902, the electronic device displays two digital viewfinders. A first displayed viewfinder (e.g., viewfinder 608-a in FIGS. 6A-6F) shows content from a first camera (e.g., wider-angle camera 602-a in FIGS. 6A-6F). A second displayed viewfinder (e.g., viewfinder 608-b in FIGS. 6A-6F) shows content from a second camera (e.g., higher-magnification camera 602-b in FIGS. 6A-6F).

At block 904, user input representing manipulation of the first viewfinder is detected. The input is instruction to pan, zoom, and/or freeze the viewfinder, for example. The input is provided on an area of display 604 or a touch-sensitive surface corresponding to the display area of the first viewfinder. Responsive to this input, the first viewfinder performs the requested operation. The second viewfinder need not be affected by this input.

At block 906, user input representing manipulation of the second viewfinder is detected. The input is instruction to pan, zoom, and/or freeze the viewfinder, for example. The input is provided on an area of display 604 or a touch-sensitive surface corresponding to the display area of the second viewfinder. Responsive to this input, the second viewfinder performs the requested operation. The first viewfinder need not be affected by this input.

Optionally, at block 908, user input representing an instruction to unfreeze a frozen viewfinder is detected. Responsive to the instruction, the relevant viewfinder is unfrozen and begins to dynamically display visual information received from a corresponding source camera.

At block 910, user input representing an instruction to store visual content from the first and second cameras, consistent with the composition as presented in the first and second viewfinders, is detected. Responsive to this user input, the electronic device creates a still image containing content from the first and second cameras and stores the still image into long-term storage such as a non-volatile memory. In some embodiments, content from the first and second cameras are stored side-by-side to provide the appearance of a “diptych.” In some embodiments, the still image is stored into a library of visual content, such as into a library of images and videos.

FIG. 10 is a flow diagram illustrating exemplary process 1000 for providing viewfinder zoom capabilities using multiple cameras in accordance with some embodiments, such as those described above with reference to FIG. 7. In some embodiments, process 1000 is carried out by device 700 (FIG. 7), which is, optionally, electronic device 100 or 300 (FIGS. 1A and 3A).

At block 1002, the electronic device displays two digital viewfinders. A first displayed viewfinder (e.g., viewfinder 708-a in FIG. 7) shows content from a first camera (e.g., wider-angle camera 602-a in FIG. 7). A second displayed viewfinder (e.g., viewfinder 708-b in FIGS. 7A-7F) shows content from a second camera (e.g., higher-magnification camera 702-b in FIGS. 7A-7F). Optionally, at block 1004, user input representing manipulation of the first and/or second viewfinder is detected. The input is instruction to pan and/or zoom a viewfinder, for example. The user input may result in viewfinders 708-a and 708-b having different visual characteristics.

At block 1006, user input representing an instruction begin recording (e.g., storing) content from the first and second cameras as seen in viewfinders 708-a and 708-b, respectively, is detected. At block 1008, responsive to the user input, the electronic begins to store a first and a second visual media using content from the first and second camera based on the composition of the first and second viewfinders, concurrently.

In some embodiments, concurrently storing a first and second visual media includes concurrently recording two videos, concurrently storing two still images, or concurrently recording a digital video and storing one or more still images. In some embodiments, concurrently storing a first and second visual media includes storing the first and second visual media in a memory such as a non-volatile memory. In some embodiments, the first and second visual media components are stored as a single file or are other associated with one another. At block 1010, the stored visual media is displayed among a collection of media objects.

At block 1012, upon user selection of a graphical user interface element representing the stored visual media, the stored visual media is played-back on a display of the electronic device.

In accordance with some embodiments, FIG. 11 shows a functional block diagram of an electronic device 1100 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments, including those described with reference to the user interfaces of FIGS. 5A-5T.

As seen in FIG. 11, exemplary electronic device 1100 includes display unit 1102 configured to display graphical objects including the digital viewfinders described above; input interface unit 1104 configured to detect user input. Optionally, device 1100 includes touch-sensitive surface unit 1106 either as part of or operatively coupled to input interface unit 1104 configured to detect touch input. In some embodiments, touch-sensitive surface unit 1106, when present, is separate from display unit 1102. In some embodiments, touch-sensitive surface unit 1106, when present, forms a touch screen with display unit 1102. Device 1100 also includes camera units 1106 and 1108 configured to capture visual content; memory unit 1110 configured to store content captured by one or more of the cameras; and non-visual media capturing unit 1112 configured to capture non-visual media such as audio. Device 1100 also includes processing unit 1114. In some embodiments processing unit 1114 supports an input detection unit 1116 that is configured to detect input via input interface unit 1106; viewfinder 1118 zooming unit configured to provide zooming features for digital viewfinder(s) displayed via display unit 1102; viewfinder panning unit configured to pan the contents of digital viewfinder(s) displayed via display unit 1102; parallax adjustment unit 1122 for reducing the effects of parallax caused by the different locations of camera units 1108 and 1110 with respect a point of interest; and display enabling unit 1124 to enable the display of content on display unit 1102.

As display unit 1102 is displaying (e.g., with display enabling unit 1124) a digital viewfinder having content from one of a first and a second camera (e.g., camera units 1108 or 1110) displayed at a zoom setting, processing unit 1114 is configured to: detect (e.g., with input detection unit 1116) user input representing an instruction to store visual media; in response to detecting the input representing the instruction to store visual media and in accordance with a determination that the zoom setting is below a threshold zoom value; store visual media using content from the first camera (e.g., into visual media storing unit 1112); and in response to detecting the input representing the instruction to store visual media and in accordance with a determination that the zoom setting is above the threshold zoom value, store visual media using content from the second camera (e.g., into visual media storing unit 1112).

In some embodiments, first camera unit 1108 has a first focal length and the second camera unit 1110 has a second focal length different than the first focal length. In some embodiments, first camera unit 1108 has a fixed focal length and second camera unit 1110 has a fixed focal length. In some embodiments, second camera 1110 has a longer focal length than first camera 1108. In some embodiments, the fields of view of the first camera 1108 and the second camera 1110 overlap by at least fifty percent.

In some embodiments, processing unit 1114 is configured to enable display (e.g., with display enabling unit 1124) the digital viewfinder via display unit 1102 by enabling display of content from first camera unit 1108 (e.g., a wider-angle camera) in the digital viewfinder, in accordance with a determination (e.g., by viewfinder zooming unit 1118) that the zoom setting is below the threshold zoom value. In some embodiments, processing unit 1114 is configured to enable display (e.g., with display enabling unit 1124) the digital viewfinder via display unit 1102 by enabling display of content from second camera 1110 (e.g., a higher-magnification camera) in the digital viewfinder, in accordance with a determination (e.g., by viewfinder zooming unit 1118) that the zoom setting is above the threshold zoom value.

In some embodiments, processing unit 1114 is configured to: enable display (e.g., with display enabling unit 1124), via display unit 1102, of the digital viewfinder by enabling display of content from first camera 1108 (e.g., a wider-angle camera) at a zoom setting lower than the threshold zoom value; detect (e.g., through input detection unit 1116) input representing a request to set the zoom setting to a value greater than the threshold zoom value; and zoom (e.g., with viewfinder zooming unit 1118) the digital viewfinder displayed on display unit 1102 by displaying content from first camera 1108 (e.g., a wider-angle camera) and then switching to displaying content from second camera 1110 (e.g., a higher-magnification camera) in response to detecting the input representing the request to set the zoom setting to a value greater than the threshold zoom value.

In some embodiments, processing unit 1114 is configured to zoom (e.g., with viewfinder zooming unit 1118) the digital viewfinder by performing a digital zoom operation on content from first camera 1108 (e.g., a wider-angle camera), where the first camera has a wider field of view than second camera 1110 (e.g., a higher-magnification camera), before switching (e.g., with viewfinder zooming unit 1118) to displaying content from second camera 1110.

In some embodiments, processing unit 1114 is configured to: detect (e.g., with input detection unit 1116) a user's specification of a point of interest in the digital viewfinder, when switching (e.g., with viewfinder zooming unit 1118) from displaying content from first camera 1108 (e.g., a wider-angle camera) to displaying content from second camera 1110 (e.g., a higher-magnification camera), adjust the relative positions of the displayed content from first camera 1108 and the displayed content from second camera 1110 (e.g., a higher-magnification camera) to reduce the appearance of parallax at the point of interest (e.g., with viewfinder zooming unit 1118).

In some embodiments, processing unit 1114 is configured to: enable display (e.g., with display enabling unit 1124) the digital viewfinder on display unit 1102 by enabling display of content from first camera 1108 (e.g., wider-angle camera) at a zoom setting lower than the threshold zoom value; and detect (e.g., with input detection unit 1116) input representing a request to set the zoom setting to a value greater than the threshold zoom value. In some embodiments, processing unit 1114 is configured to: in response to detecting the input representing the request to set the zoom setting to a value greater than the threshold zoom value, zoom (e.g., with viewfinder zooming unit 1118) the digital viewfinder to display content from first camera 1108 (e.g., a wider-angle camera) at the threshold zoom value.

In some embodiments, the input representing the request to set the zoom setting to a value greater than the threshold zoom value is a first input, and processing unit 1114 is configured to: after detecting the first input and while the zoom setting is set to the threshold zoom value, detect (e.g., with input detection unit 1116) a second input representing a second request to set the zoom setting to a second value greater than the threshold zoom value. In some embodiments, processing unit 1114 is configured to: in response to detecting the second input, zoom (e.g., with viewfinder zooming unit 1118) the digital viewfinder to display content from second camera 1110 (e.g., a higher-magnification camera) at the second value of zoom setting.

In some embodiments, processing unit 1114 is configured to enable display (e.g., with display enabling unit 1124), via display unit 1102, in the digital viewfinder a visual indication of the zoom setting. In some embodiments, processing unit 1114 is configured to enable display (e.g., with display enabling unit 1124), via display unit 1102, in the digital viewfinder a visual indication of the threshold zoom value.

In some embodiments, processing unit 1114 is configured to zoom (e.g., with viewfinder zooming unit 1118) the digital viewfinder to display content from second camera 1110 (e.g., a higher-magnification camera) at the requested zoom setting value by displaying, via display unit 1102, a transition effect in the digital viewfinder indicative of the zoom setting changing from a value at the threshold to a value above the threshold. The transition effect transitions between an image captured by first camera 1108 (e.g., a wider-angle camera) and an image captured by second camera 1110 (e.g., a higher-magnification camera), for example.

In some embodiments, first camera 1108 has a wider field of view than second 1110 camera and the digital viewfinder displayed on display unit 1102 comprises content from first camera 1108, regardless of the zoom setting.

In some embodiments, first camera 1108 and second camera 1110 have overlapping fields of view, and processing unit 1114 is configured to, while display unit 1102 is displaying content from one of the first and second cameras 1108 and 1110 in the digital viewfinder (e.g., with display enabling unit 1124), detect (e.g., with input detection unit 1116) one or more taps on the touch-sensitive surface unit. In some embodiments, processing unit 1114 is configured to, in response to detecting the one or more taps, switch (e.g., with viewfinder zooming unit 1118) the displayed content of the digital viewfinder to content from the other of the first and second cameras.

In some embodiments, processing unit 1114 is configured to, while display unit 1102 is displaying (e.g., with display enabling unit 1124) content from one of the first and second cameras 1108 and 1110 in the digital viewfinder, enable display via the display unit a camera selection affordance, the camera selection affordance displaying content from the other camera of the first and second cameras. The one or more taps is detected at a location of the touch-sensitive surface unit corresponding to the camera selection affordance in some examples.

In some embodiments, processing unit 1114 is configured to apply digital zooming (e.g., with viewfinder zooming unit 1118) to content from first camera 1108 and/or second camera 1110. In some embodiments, processing unit 1114 is configured to pan (e.g., with viewfinder panning unit 1118) content from first camera 1108 and/or second camera 1110 responsive to user input detected through input detection unit 1116.

The operations described above with respect to FIGS. 8A-8C are, optionally, implemented by components depicted in FIGS. 1A-1B, 3, or FIG. 11. For example, detecting operation 804 is, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects user input on an input device, and event dispatcher module 174 delivers the event information to application 143. A respective event recognizer 180 of application 143 compares the event information to respective event definitions 186, and determines whether the input represents an instruction to store viewfinder content. When a respective event or sub-event is detected, event recognizer 180 activates an event handler 190, which may use or call data updater 176, object updater 177, or GUI updater 178 to perform corresponding application updates. It would be clear to a person of ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B and/or FIG. 3.

It is understood by persons of skill in the art that the functional blocks described in FIG. 11 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. For example, units 1102-1112 can have associated “controller” units that are operatively coupled with the respective unit and processing unit 1114 to enable operation. These controller units are not separately illustrated in FIG. 11 but are understood to be within the grasp of one of ordinary skill in the art who is designing a device having units 1102-1112 such as device 1100. The description herein thus optionally supports combination, separation, and/or further definition of the functional blocks described herein.

In accordance with some embodiments, FIG. 12 shows a functional block diagram of an electronic device 1200 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments, including those described with reference to the user interfaces of FIGS. 6A-6G.

As seen in FIG. 12, exemplary electronic device 1200 includes display unit 1202 configured to display graphical objects including the digital viewfinders described above; input interface unit 1204 configured to detect user input. Optionally, device 1200 includes touch-sensitive surface unit 1206 either as part of or operatively coupled to input interface unit 1204 configured to detect touch input. In some embodiments, touch-sensitive surface unit 1206, when present, is separate from display unit 1202. In some embodiments, touch-sensitive surface unit 1206, when present, forms a touch screen with display unit 1202. Device 1200 also includes camera units 1206 and 1208 configured to capture visual content; memory unit 1210 configured to store content captured by one or more of the cameras; and visual media capturing unit 1212 configured to capture visual media such as videos and/or images (and optionally, non-visual media such as audio). Device 1200 also includes processing unit 1214. In some embodiments processing unit 1214 supports an input detection unit 1216 that is configured to detect input via input interface unit 1206; viewfinder zooming unit 1218 configured to provide zooming features for digital viewfinder(s) displayed via display unit 1202; viewfinder panning unit configured to pan the contents of digital viewfinder(s) displayed via display unit 1202; viewfinder freezing unit 1222 for freezing the content of one or more digital viewfinders displayed on display unit 1202; and display enabling unit 1224 for enabling the display of content on display unit 1204.

In some embodiments, processing unit 1214 is configured to: enable display (e.g., with display enabling unit 1224) via a first portion of display unit 1202, of a first digital viewfinder showing content from first camera 1208, and enable display (e.g., with display enabling unit 1224) via a second portion of display unit 1202, of a second digital viewfinder, the second digital viewfinder displaying content from second camera 1210; detect (e.g., with input detection unit 1216), a first input representing an instruction to zoom the first digital viewfinder; in response to detecting the first input, zoom the first digital viewfinder independently of the second digital viewfinder (e.g., with viewfinder zooming unit 1218); detect (e.g., with input detection unit 1216), a second input representing an instruction to freeze the first digital viewfinder; and in response to detecting the second input, freeze (e.g., with viewfinder freezing unit 1220) the first digital viewfinder independently of the second digital viewfinder.

In some embodiments, the first input is a de-pinching input located on a portion of touch-sensitive surface unit 1204 corresponding to the first digital viewfinder displayed on display unit 1202.
